CHAIN CONVEYER.

Specification of Letters Patent.

Application filed June 16, 1909.

Patented Nov. 29, 1910.

Serial no. 502,519.

To all whom it may concern:

Be it known that I, Tnoims A. COLEMAN, a citizen of the United States,residing at Longville, Louisiana, have invented a certain new and usefulImprovement in Chain Conveyers, of which the following is a full, clear,and exact description, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to theaccompanying drawings, forming part of this soecification.

My invention relates to new and useful improvements in chain conveyorsparticularly adapted for use in carrying off refuse lumber fromsawmills, etc, and is designed as an improvement on .the chain conveyershown and described in an application for United States Letters Patentfiled by me March 11, 1909, serially numbered 482,751.

The essential features of my present invention reside in a two-partflight which may be easily and quickly attached to one of the verticallinks of a conveyer chain in such a manner as to not impair the strengththereof.

I propose to form the main body portion of the flight in one piece, andto provide the same with a head which engages one-half of the bodyportion of a chain length, there being a cap or block rigidly fixed tothe head for engaging the opposite half of the body portion of the link.

To the above purposes, my invention consists in certain novel featuresof construction hereinafter described and claimed.

In the drawings :Figure 1 is a plan view of a portion of a conveyerchain provided with a flight of my improved con struction. Fig. 2 is arear elevation of the flight, showing one of the links of the conveyerchain in section. Fig. 3 is a section taken on the line 3-3, Fig. 1.Fig. t is an elevation of the conveyer chain, showing the end of one ofthe flights thereon. Fig. 5 is a cross section taken on the line 55,Fig. 1.

The main body portion of the flight of my improved chain conveyercomprises a ver tically-disposed plate 1, the front face of which ispreferably concave in cross section in order to overcome any tendency ofthe flight to climb or ride over the refuse in the conveyer trough.Formed integral with one end of this plate is a head 2, in the underside of which is formed a groove 3 which occupies a positionapproximately at right angles to the plane occupied by the plate 1.Formed integral with the rear side of the plate 1, midway between thetop and bottom edges thereof, is a horizontally-disposed reinforcingflange 4, one end of which is integral with the upper portion of thehead 2.

5 designates a block in the top of which is formed atransversely-disposed groove 6, said block being substantially of thesame shape as is the head 2. This block 5 occupies a position on top ofthe head 2 and formed integral with one side of said block is an ear 5which rests on top of the flange et at the point where the same joinsthe head 2, and passing through said ear and flange is a rivet 7 or likefastening device.

When my improved flight is applied to a conveyer chain, the head 2 isengaged on the lower half of one of the vertical links of the chain andthe block 5 is now positioned on top of the head 2 beneath the upperhalf of the vertical link and said block is fixed to the body of theflight by means of the rivet 7. Thus the two parts of the flight arerigidly connected to one another and to the chain.

A chain conveyer of my improved construction is comparatively simple,very strong and durable, and the flights, which are composed of but twoparts, are easily and quickly applied to the conveyer chain.

It will be readily understood that minor changes in the construction andform of my improved conveyer can be made and substi-.

tuted for those herein shown and described without departing from thespirit of my invention.

I claim:

1. The combination with a conveyer-chain, of a flight comprising avertically disposed plate, a head on the end thereof, in the undersideof which head is formed a link receiving groove, a reinforcing flangeintegral with the rear side of the plate, and with the head, a blockpositioned on the head, in which block is formed a link receivinggroove, an extension 011 the block which overlies a portion of thereinforcing flange, and fastening means passing through the extension,and the reinforcing flange.

2. The combination with a conveyer chain, of a flight comprising avertically disposed plate, a head formed on one end thereof, there beinga link receiving groove formed in the under side of the head, areinforcing flange on the rear side of the plate, a block 2 signature inthe presence of two witnesses, positioned on the head and provided witha I this 9th day of June 1909. lin I receiving groove an ear )rojeotin wfrom said block and engaging the} reinfore t THOMAS COLEMAN 5 ingflange, and a fastening device passing \Vitnesses:

through said ear and the flange. I H. T. RoEHL,

In testimony whereof I hereunto affiX my E. V. ZOOMER.
